Vitamins

The word “vitamin” goes back to the Polish scientist Casimir Funk in 1912. He was studying a substance in the layer that covers rice. This substance was believed to cure a disease called beriberi.

Funk believed the substance belonged to a group of chemicals known as amines. He added the Latin word «vita,» meaning life. So he called the substance a “vitamine” — an amine necessary for life.

Scientists have discovered fourteen kinds of vitamins. They are known as vitamins A, the B group, C, D, E and K. Scientists say vitamins help to carry out chemical changes in cells. If we do not get enough of the vitamins we need in our food, we may develop a number of diseases.

This brings us back to Casmir Funk. His studies of rice were part of a long search for foods that could cure disease.

One of the first people involved in that search was James Lind of Scotland. In the 1740s, Lind was a doctor for the British navy. He investigated a problem that had existed in the navy for many years.

The problem was the disease scurvy. So many sailors had scurvy that the navy’s lost some of its strength. The sailors were weak from bleeding inside their bodies. Even the smallest wound would not heal. Doctor Lind thought the sailors were getting sick because they failed to eat some kinds of foods when they were at sea for many months.

Doctor Lind separated twelve sailors who had scurvy into two groups. He gave each group different foods to eat. One group got oranges and lemons. The other did not. The men who ate the fruit began to improve within seven days. The other men got weaker. Doctor Lind was correct. Eating citrus fruits prevents scurvy.

Types of Vitamins

Vitamin A helps prevent skin and other tissues from becoming dry. It is also needed to make a light-sensitive substance in the eyes. People who do not get enough vitamin A cannot see well in darkness. Their eys may get dry. This can result in infections and lead to blindness.

Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.

Vitamin B-one is also called thiamine. Thiamine changes starchy foods into energy. It also helps the heart and nervous system work well. Without it, we would be weak and would not grow. We also might develop beriberi. Apart from rice thiamine is found in beans , peas, nuts, meat and fish.

Another B-vitamin is niacin. It helps cells use food energy. It also prevents pellagra -a disease that causes weakness, reddish skin and stomach problems. Niacin is found in meat, fish and green vegetables.

Vitamin B-12 helps produce red blood cells. It is found naturally in foods such as eggs, meat, fish and milk products. It also helps babies of pregnant mothers before they are born . Vitamin B-12 is found in green leafy vegetables and other foods and citrus fruits. In some countries, it is added to products like bread.

Vitamin C is needed for strong bones and teeth, and for healthy blood. It also helps wounds heal quickly. Because our body stores little vitamin C we must get it every day in foods such as citrus fruits, tomatoes and cabbage.

Vitamin D helps make calcium in the blood. Calcium is needed for nerve and muscle cells to work normally. It also is needed to build strong bones. Ultraviolet light from the sun changes a substance in the skin into vitamin D. Fish liver oil also contains vitamin D. In some countries, milk producers add vitamin D to milk so children will get enough.

Vitamin K is needed for healthy blood. It thickens the blood around a cut to stop bleeding. Bacteria in the intestines normally produce vitamin K. It can also be found in pork products, liver and in vegetables like cabbage, and spinach.

Some people fear they do not get enough vitamins from the foods they eat. So they take products with large amounts of vitamins. They think these products or vitamin supplements will improve their health and protect them from disease.

Experts note that taking too much of some vitamins can be harmful. People should be sure to discuss what vitamins they take with their doctors. This is because some vitamins can cause harmful effects when mixed with medicines.

The importance of vitamins for our health can hardly be overestimated. Probably, everyone has heard that vitamins and minerals are part and parcel of a healthy diet. Unfortunately, statistics says that today people all over the world consume too much calories and too little essential nutrients and vitamins.

Lack of vitamins, known as vitamin deficiency, influences the state of our skin, hair, nails, teeth and bones.

In more serious cases it can cause heavy diseases – spasms, loss of hair and teeth, loss of vision, hepatic disorders, skin diseases, and many others.

There are over thirty vitamins, and some of them are incorporated into groups. Vitamins themselves don’t have any nutritional value, they don’t contain any calories and can’t serve as sources of energy. They relate to micronutrients that are contained in food. So, to be healthy, we need to eat several types of food: fruit and vegetables, fish and meat, and milk products.

Vitamins can be divided into two large groups: fat-soluble and water soluble ones. As the term suggests, water soluble vitamins are dissolved in water, while the fat-soluble ones are dissolved only in fats. The first group includes vitamin C and B-group vitamins. Such vitamins as A, E, D and K belong to the second group, and they can be stored in our organism. That’s why we lack vitamins of the first group more often.

Vitamin B9, which is also known as folic acid is a very important element for women. It is absolutely indispensable during pregnancy and breastfeeding. Also it regulates nervous system activity and helps to combat depression.

It can be found in green vegetables, liver, wholegrain bread, honey.

Vitamin E (Tocopherol), is found in vegetable oil, green leafy vegetables, wheat germ, egg yolk, butter and liver. It functions as an «antioxidant» for other vitamins, preventing C and A and other fatty-acid proteins from being burnt up prematurely; in this way it helps prevent cell-membrane damage.

Most experts believe that Vitamin E deficiency can only occur in extreme causes of malnutrition, but this doesn’t mean that supplements might not be useful. One recent study found that Vitamin E helped to prevent angina (cardiovascular distress), for reasons not yet understood.

So, if you wish to be healthy, energetic and have a healthy appearance, pay careful attention to your diet. Try to choose natural food containing all basic vitamins and minerals. Your daily ration must include enough fresh fruit and vegetables, crude oil and wholegrain bread. Also try to eat fish or sea products at least twice a week.
